What do we really know?

Knowledge, the engine of our existence and the foundation of our humanity, has intrigued philosophers for centuries. In this book, we dive into an analysis of its nature, exploring how history's greatest minds have attempted to define and unravel this elusive concept. From the classic Platonic notion of "justified true belief" to the modern uncertainties raised by Edmund Gettier, each chapter reveals the nuances of an essential question: what does it mean to know?Through an in-depth philosophical approach, this text not only reviews iconic theories by authors such as Descartes and Hume, but also examines the tensions, limits, and paradoxes that have marked the development of human thinking about knowledge. It is an intellectual journey that invites the reader to reflect and join a timeless dialogue on one of the most fundamental pillars of our understanding of the world and ourselves.
